These modifications mean that each of the power generation units at the two power stations will have to be turned off while the height of the boilers is increased, placing further strain on the national grid.

Both power stations were expected to be completed in 2015 when they were first announced in 2007, but De Ruyter has now said Medupi will be completed in 2021 and Kusile in 2022.

Medupi’s total cost has risen from R80 billion to R145 billion, while Kusile’s has increased from R100 billion to R161.4 billion.

It would be so laughable if it didn’t mean that we are plunged into darkness for hours at a time.

Those app notifications have a habit of popping up just when you think you’re out of the woods, too.
